BI 1203-S is a battery isolator from Mastervolt that divides the charge current between 3 batteries with a minimum of energy loss.
Onboard systems usually consist of two or more batteries that function independently when powering the 12, 24 or 48 V consumers. These batteries require independent charging with reliable battery isolators or battery combiners.
Mastervolt’s BI battery isolators are based on conventional diode technology. The diode voltage drop (ca. 0.6 V) can be compensated for by adapting the output voltage of the connected charger or alternator. Mastervolt battery chargers and Alpha Pro MB charge regulators come as standard with automatic voltage drop compensation.
Compact and lightweight
The Mastervolt BI battery isolators are compact and fully solid state, preventing wear. The weight varies from 580 to 1300 grams.
Robust and durable
Completely corrosion-proof material with aluminium heat sinks. The electronic components are encased in synthetic materials, the BI models have molded diode splitters.
The synthetic end plates feature connection lugs, the solid bolt connections with nuts and locking rings ensure easy installation.
